4k monitors issue - MM moves between screens after unlocking computer and loses windows scaling & column widths

[MarcLister]

In late January 2026 I changed from 3x 27" 2560x1440 monitors to 3 x 27" 4k monitors (3840x2160). The build of MM was 2024.2.1 3203 and I've installed each new beta build as it came along and am currently on 3220.

When I changed to the 4k monitors I noticed a few issues with MediaMonkey. When I lock the computer and then unlock it MediaMonkey will change which monitor it is showing on. I typically have it on the right most monitor but it will move to the center monitor and I have to drag it back.

The program will also lose its scaling setting of 150% set in Windows. When I drag it back to where it was before unlocking it will resume its correct windows scaling.

Last, but not least, the column widths I set change so I have a narrow left hand pane and have to widen it, then the right hand now playing pane does the same so I have to widen that and take up the slack from the centre pane.

Is there any known issues, and fixes, for 4k monitors? I get this is slightly a first world issue but the issues are quite annoying to me.

Hi. I only have one 4K and two Full HD monitors, and I haven’t experienced such issues. Have you changed anything else besides the monitors (like the connection method – HDMI, DisplayPort)?

[MarcLister]

Nope. I am using DisplayPort to DisplayPort. I had changed the graphics card from an Nvidia one to AMD but that was a few weeks before the monitors changed and MediaMonkey was fine on AMD graphics until the monitors changed.

I think DisplayPort can be root of the issue as it works as PnP and when display is turned off, it is disconnected from the system like when you remove display at all.

Hi PetrCBR. I am not turning the displays off. I lock the computer and when I return MM has moved from the right-most screen to the central screen. The power setting for my monitors is to turn them off after 30 minutes. If I lock the computer and come back within a few minutes then the issue happens.
